Create a new trailer inspired by this selected film. The example combines two generated films, replacement shots, retiming, a brief dip to black and English subtitles added in post. This is a brief for a new reference-guided film, not the original generation prompt or a request to reproduce the finished edit exactly. Act as the director and create a complete 15-second, 9:16 vertical, English-language trailer with sound for the interactive story UNCLAIMED. Use the world, player premise, and reference images below to independently decide the storytelling, cast appearances, shots, editing, performances, and sound. A first-time viewer should understand what kind of place this is, who they would be in the story, and what they are about to face. It is autumn 1987 in Keeler, a small town in a valley in the northern United States. There are schools, wooden houses, bicycles, cassette recorders, and a reservoir that submerged the old town. Everyday life appears to carry on normally. But when someone disappears, the town begins erasing the traces that they ever existed: a line vanishes from the school roster, a bedroom becomes something else, and a family gradually forgets it ever had that child. You are a thirteen- or fourteen-year-old kid in town. Last night your best friend Denny rode downhill toward home and never arrived. The next morning his mother still warmly invites you in for breakfast, but can no longer remember whose friend you are. You are one of the few people who still clearly remembers him. Beneath the reservoir, the old town's houses, school, and church are still standing. Its last water tender never received an order to stop working. He is still counting, filing, and looking after everything in his jurisdiction. He takes people when no one is thinking of them. Once even their names and the specific memories of their lives have been forgotten and they have been entered in his ledger, they cannot return. You have no superpowers and no adults backing you up. You have a bicycle, a pen, a few friends, and memories that have not yet been erased. Writing down names, preserving specific details, and finding other people who still remember are how you resist the forgetting and search for Denny. The emotional appeal is the real friendship between these kids and the discovery that the familiar world is quietly denying that someone you love ever existed. Reference image 1 is the existing game cover. Use it only as a visual style reference and interpret its style yourself. Generate fresh moving scenes rather than inserting, enlarging, or simply animating the supplied still image. The input images are reference material, not finished video frames; do not carry their resolution limits or compression noise into the newly generated imagery. Reference image 2 is Ruthie Kolb, Denny's sixteen-year-old sister: sharp-tongued, stubborn, and still remembering her brother. Reference image 3 is Wade Pruitt, thirteen: talkative, easily scared but loyal, with his portable cassette recorder. Reference image 4 is Junie Sowell, thirteen: bold, quick to laugh, and living in the trailer park outside town. Reference image 5 is Merle Tice, the sixty-two-year-old mailman who knows every household. Reference image 6 is Dana Selk, the thirty-four-year-old water authority field specialist: polite, professional, and carrying forms on a clipboard. Reference image 7 is the Tender, the silent water tender in a raincoat who appears by the receding waterline. Choose which of these characters to feature as the story requires; all six do not need to appear. Whenever one appears, preserve the face, age, and distinctive appearance of the corresponding character reference while generating a new performance and scene. No portrait of Denny is provided: convey him through his name, his absence, and the traces he left, without inventing a visible face for him. The player has no fixed appearance; preserve room for viewers to imagine themselves in that role. Generate the complete soundtrack together with the video: clear, brief, natural English narration or character dialogue, environmental sound, and an original score. You decide the spoken wording and how to use sound. Make the player's predicament understandable while leaving a compelling mystery. The title is UNCLAIMED. The viewer should want to enter Keeler and personally search for the friend everyone is forgetting.

They forgot him, like he was never even there. But I remember. We remember. And he's just still waiting. And he's still waiting.

Move. 16 years gone, and I'm not just home. [Unclear phrase; the approved subtitle reads: “I’m the wild card.”] The game isn't about winning. It's about who gets to rearrange the chairs.

I make beds, I remove stains, I'm just a contract worker. But one day, I picked up the wrong folder. Good, you're here. The state dinner seating chart needs your touch. Dad, she's not the aide. She changes my sheets. Now I'm solving state-level problems with a lint roller.

About

Some moments need time: a camera revealing a room, a sculpture slowly opening, light changing across a landscape. For creators planning a gradual reveal or several connected actions, Seedance 2.5 includes a longer clip option in the current model configuration. Start from words or an image, describe how the scene begins and ends, and choose from the length options shown in the entry. Review the full result for pacing and continuity.

Questions

Can Seedance 2.5 make a longer clip?

The current model configuration includes a 30-second option. Check the length choices actually shown for your request before sending, and use a longer setting only when the scene needs it.

Does a longer duration guarantee one continuous take?

No. State that you want a continuous take and describe its camera movement, but review the output for cuts and continuity. The supported duration is a setting, not a guarantee about the resulting shot.

Can I start from my own image?

Yes. Use Image to Video and add a start frame you have permission to supply. In this mode, Seedance 2.5 follows the source image’s aspect, so prepare its composition for the screen you want.

Are its resolution options the same as Seedance 2.0?

The catalog lists different resolution options for the two models. Check each specification table and the active settings before choosing; a newer model name does not by itself mean a larger output.

How do I write a longer scene without overloading the prompt?

Keep one setting and a clear progression. Describe the opening, the main change and the ending, then state the camera path. Avoid packing unrelated scenes into the same request.
